1.3. Restrictions for use
The sample must not contain any particles, which may block the
flow cell. Sufficient sample flow is coercive for the correct function
of the instrument.
If the sample contains only little disinfectant concentrations, or
there is the danger of biological growth, we recommend to use the
optional Cleaning module from Swan.
WARNING

A part of the sample flows through the photometer inlet [C] into the

the peristaltic pump [D] and mixed with the sample. The mixed
sample flows through the photometer [K] where the free available
chlorine is measured.

Total chlorine 1 After the measurement of free available chlorine is finished the so-
lenoid valve [G] is energized for a short time and reagent [O] is
added to determine total chlorine 1.
Total chlorine 2 To ensure the necessary reaction time of 2 min. for the determina-
tion of total chlorine 2, the sample flow is stopped by the solenoid
valve [J]. After the time has elapsed, total chlorine is measured and
solenoid valve [J] opens again.

AMI Codes-II CC
Product Description
General It is distinguished between two different kinds of measurement:
Free available chlorine (fac) measurement
Overall measurement including free available chlorine (fac),
total chlorine 1 (tc1) and total chlorine 2 (tc2).
The Interval fac and the Interval tc2 can be set individually:
Interval fac between 0 and 12 min.
Interval tc2 between 0 and 60 min (overall measurement).
NOTICE: If the fac interval is set to zero, it is nevertheless
measured in the overall measurement.
The default setting for fac measurement interval is 5 min and for
overall measurement interval 20 min.
Time
sequence of an
overall
measurement
The blue bar represents the sample flow through the photometer.
At the beginning the solenoid valve [J] is de-energized and the
sample flows through the photometer. A short time before the measurement starts, a zero point measurement is performed. Then the
peristaltic pump starts and a small portion of the reagents “Oxycon
on-line DPD” and “OXYCON ON-LINE Buffer” is pumped into the
mixing chamber. During this time, the solenoid valve [G] is de-energized and the “Oxycon On-line KI” circulates between the peristaltic
pump and the valve block.
A short time after, if the mixture is in the photometer, the free available chlorine (fac) of the sample is measured.
After about 25 sec the peristaltic pump starts again. Now the solenoid valve [G] is energized and a small portion of the reagents
“Oxycon on-line DPD”, “OXYCON ON-LINE Buffer” and “Oxycon
On-line KI” is pumped into the mixing chamber.
A short time after, the solenoid valve [J] is energized and the sample flow through the potometer is stopped. Immediately after that,
the tc 1 is measured.
The “calculated monochloramine” (cmc) is calculated and displayed.
After about 120 sec the tc 2 is measured and then the “calculated
dichloramine” (cdc) and the “calculated combined chlorine” (ccc)
are calculated and displayed.
After the measurement is finished, the solenoid valve [J] is de-energized and sample flows through the photometer and a flush time of
2 minutes follows.

The programmed measuring intervals of tc2 [F] and fac [G] may
overlap each other.
The tc2 measurement has priority and therefore always takes place
in the programed measuring interval [F]. The fac measurement is
filled in the gaps [H] of the overall measurement and may be shifted
(orange arrow) in respect to programmed interval. If 2 fac measurements are programmed during a overall measurement one of them
is cancelled (red arrow).

3.1. Installation Check List
Check Instrument’s specification must conform to the National Electrical
Code, all state and local codes, and all plant codes and standards
for electrical equipment.
On site requirements
Installation Mount the instrument in vertical position.
Electrical Wiring Do not switch on the Instrument until all electrical connections are
If ordered:

100– 240 VAC ( 10%), 50/60 Hz ( 5%) or 24 VDC (±10%),
isolated power outlet with ground connection and 30 VA.
Sample line with min. 10 l / h and 0.15 – 2 bar.
Waste line with pressure free drain.
Display should be at eye-level.
Mount the filter, filter vessel, and constant head cover. Connect the
sample and waste line. See Connecting Sample and Waste, p. 21
made.
Connect all external devices like limit switches, current loops and
pumps.
Connect power cord.
See Electrical Connections, p. 27
See Install the Option pH, p. 23
Insert the suction lances combined with level detector.

3.2. Mounting of Instrument Panel
Mounting re-
quirements
Make 3 manual measurements. Use a high quality photometer,
e.g. Chematest from Swan. Calculate average value and compare
this value to the value, indicated by the AMI. If necessary, correct
the value. The zero point is done automatically before each measurement.
The first part of this chapter describes the preparing and placing of
the system for use.
The instrument must only be installed by trained personnel.
Mount the instrument in vertical position.
For ease of operation mount it so that the display is at eye
level.
For the installation a kit containing the following installation
material is available:
– 6 Screws 6x60 mm
– 6 Dowels
– 6 Washers 6.4/12 mm
The instrument is only intended for indoor installation.
For dimensions see Dimensions, p. 17.
